Underwater electric field receiver and emitter

This device is capable of emitting and receiving electic field underwater, in fresh and sea (salt) water. The technology is used multiple reconfigurable dipoles for emitting and sensing channels, extremelly low-noise amplifiers with adjustable filters, high-performance embedded microcontrollers for data pre-processing. Device is connected with standard PC/laptop via USB for further data processing and control.

Main features:

Receiver part

voltage mode sensing and current mode sensing

excellent signal/noise relation due to a high-resolution ADC and extremely low-noise amplifiers

capability of data fusion from several sensing electrodes

capability to store the received signals in internal memory or to send to external PC/laptop

adjustable distance between receiving electrodes

adjustable number of receiving electrodes

purpose-specific geometrical form/shape of electrodes

Emitter part

programmable voltage output and DC offsets, -25 ... +25 Volts

current limiter for each dipole

high-resolution DAC for signal generation
